The average of 50 numbers is 38. If the numbers 45 and 55 are discarded, then the average of the remaining numbers is-

A. 36.5

B. 37

C. 37.5

D. 37.52

Answer: Option C

Solution(By Examveda Team)

Sum of 50 numbers = 38 × 50 = 1900
Sum of remaining 48 numbers
= 1900 - (45 + 55)
= 1800
∴ Required average
= $$\left( {\frac{{1800}}{48}} \right)$$
= 37.5
